I'm sure this is here on this site - but sometimes looking right at it and reminding ourselves the benefits can help! The paragraph on cessation below really helped me feel a bit more normal.....!
1. I found this exerpt from www.rimrock.org
What Happens When Nicotine Is Taken For Long Periods Of Time?
Chronic exposure to nicotine results in addiction. Research is just beginning to document all of the neurological changes that accompany the development and maintenance of nicotine addiction. The behavioral consequences of these changes are well documented, however. Greater than 90 percent of those smokers who try to quit without seeking treatment fail, with most relapsing within a week. Repeated exposure to nicotine results in the development of tolerance, the condition in which higher doses of a drug are required to produce the same initial stimulation. Nicotine is metabolized fairly rapidly, disappearing from the body in a few hours. Therefore some tolerance is lost overnight, and smokers often report that the first cigarettes of the day are the strongest and/or the "best." As the day progresses, acute tolerance develops, and later cigarettes have less effect.
Cessation of nicotine use is followed by a withdrawal syndrome that may last a month or more; it includes symptoms that can quickly drive people back to tobacco use. Nicotine withdrawal symptoms include irritability, craving, cognitive and attentional deficits, sleep disturbances, and increased appetite and may begin within a few hours after the last cigarette. Symptoms peak within the first few days and may subside within a few weeks. For some people, however, symptoms may persist for months or longer.
An important but poorly understood component of the nicotine withdrawal syndrome is craving, an urge for nicotine that has been described as a major obstacle to successful abstinence. High levels of craving for tobacco may persist for 6 months or longer. While the withdrawal syndrome is related to the pharmacological effects of nicotine, many behavioral factors also can affect the severity of withdrawal symptoms. For some people, the feel, smell, and sight of a cigarette and the ritual of obtaining, handling, lighting, and smoking the cigarette are all associated with the pleasurable effects of smoking and can make withdrawal or craving worse. While nicotine gum and patches may alleviate the pharmacological aspects of withdrawal, cravings often persist.
2. When smokers quit -- What are the benefits over time?
20 minutes after quitting: Your heart rate and blood pressure drops.
(Effect of Smoking on Arterial Stiffness and Pulse Pressure Amplification, Mahmud, A, Feely, J. 2003. Hypertension:41:183.)
12 hours after quitting: The carbon monoxide level in your blood drops to normal.
(US Surgeon General's Report, 1988, p. 202)
2 weeks to 3 months after quitting: Your circulation improves and your lung function increases.
(US Surgeon General's Report, 1990, pp.193, 194,196, 285, 323)
1 to 9 months after quitting: Coughing and shortness of breath decrease; cilia (tiny hair-like structures that move mucus out of the lungs) regain normal function in the lungs, increasing the ability to handle mucus, clean the lungs, and reduce the risk of infection.
(US Surgeon General's Report, 1990, pp. 285-287, 304)
1 year after quitting: The excess risk of coronary heart disease is half that of a smoker's.
(US Surgeon General's Report, 1990, p. vi)
5 years after quitting: Your stroke risk is reduced to that of a non-smoker 5 to 15 years after quitting.
(US Surgeon General's Report, 1990, p. vi)
10 years after quitting: The lung cancer death rate is about half that of a continuing smoker's. The risk of cancer of the mouth, throat, esophagus, bladder, cervix, and pancreas decrease, too.
(US Surgeon General's Report, 1990, pp. vi, 131, 148, 152, 155, 164,166)
15 years after quitting: The risk of coronary heart disease is the same as a non-smoker's.
(US Surgeon General's Report, 1990, p. vi)
